Q13Network Design

An international company provides early warnings about tsunamis. The company plans to use IoT devices to monitor sea waves worldwide. Data collected by the IoT devices must reach the company’s infrastructure on AWS as quickly as possible. The company uses three operations centers around the world. Each operations center connects to AWS through its own AWS Direct Connect connection. Each operations center connects to the internet through at least two upstream internet service providers. The company owns provider-independent (PI) address space. The IoT devices use TCP protocols to reliably transmit the data that they collect. The IoT devices have both landline and mobile internet connectivity. The infrastructure and solution will be deployed in multiple AWS Regions. The company will use Amazon Route 53 for DNS services. A network engineer must design connectivity between the IoT devices and the services running in the AWS Cloud. Which solution will meet these requirements with the **HIGHEST** availability?

C https://docs.aws.amazon.com/global-accelerator/latest/dg/introduction-benefits-of-migrating.html https://docs.aws.amazon.com/global-accelerator/latest/dg/using-byoip.html

Should be Option B) as per the architecture given in the link https://aws.amazon.com/blogs/iot/automate-global-device-provisioning-with-aws-iot-core-and-amazon-route-53/

AWS Global Accelerator is designed to provide a highly available and performant solution for global applications. It uses anycast IP addresses to route traffic to optimal AWS endpoint locations. In this scenario, setting up an accelerator in AWS Global Accelerator with Regional endpoint groups is suitable for the distributed architecture of the IoT devices and the AWS infrastructure. Options A and B involve Amazon CloudFront and Route 53 latency-based routing, respectively, but AWS Global Accelerator is specifically designed to provide highly available, low-latency, and fault-tolerant global routing, making it a more suitable choice for this scenario. Option D, Bring Your Own IP (BYOIP) addresses, is not directly related to optimizing the connectivity for IoT devices and services in AWS, and it doesn't address the global distribution and routing requirements as effectively as AWS Global Accelerator.

C Using AWS Global Accelerator with regional endpoint groups provides the highest availability as it allows traffic to be routed to healthy endpoints in different regions. Additionally, health checks can ensure that traffic is not directed to unhealthy endpoints.

The queston is not really clear, they do not state the goal. though seem C with global accerlator can help improve HA

Hello everyone, I saw some people talking about option B. But B is wrong. It can be used but the record it would create would be CNAME and not ALIAS record. https://aws.amazon.com/blogs/iot/automate-global-device-provisioning-with-aws-iot-core-and-amazon-route-53/ The option explicitly talks about using Alias and iots cannot be configured as a registry for an alias. Option C is correct!

Quick hack: Once its a global service that involves TCP or UDP, Eliminate the options quickly by pointing to Global Accelerator

C. AWS Global Accelerator (plus Route 53 for DNS) is the AWS-recommended, highest-availability architecture for your scenario. Route 53 will still be used—for DNS management and to point IoT devices to Global Accelerator IPs. Global Accelerator is for highly available, TCP-based, multi-region, real-time failover routing.

It says the "Highest" throughtput, anything with VPN is limited to 1.25 Gbps per tunnel.

The wording of this question is kinda odd.So bouncing between B and C For me the following makes me think C is the right option "A network engineer needs to design connectivity between the IoT devices and the services that run in the AWS Cloud" Kind of a tricky one this.

B 1

"The solution must use route 53 dns" B

I think that it's correcty answer is B.

C 1

Definitely C

Long case scenario, giving snippets of information; but C (AGA) felt the most appropriate solution for high availability and delivering data so quickly (through AWS backbone).

I think that it's correct answer is C according to SPOTO products.

B 1

Highest SLA requirement indicate that route 53 has to be used, it is the only service that gives 100% availability . https://aws.amazon.com/route53/sla/ , the same page for Global Accelerator lists 99.9% only. I would choose B over C for this reason.
